My present invention has for its object to provide an extremely simple and highly ef-- ficient stanchion for barn equipment that is very strong, rigid and durable, that cannot be accidentally released and that is easy'to.

operate andof comparatively small cost to manufacture. l V, e

To the above end, generally stated, theinvention consists of the novel devices and combinations of devices hereinafter described and defined in the claims. In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings:

Fig. 1 is a fragmentary perspective" view of a stall structure equipped with the ima proved stanchion;

Fig. 2is a top view of the stanchion, on an enlarged scale, removed from the stall;

Fig. 3 is afragmentary side elevation of the same with some parts shown in vertical section and other parts shown in different positions by means of broken lines; I

Fig. 4 is a bottom view of the stanchion; Fig. 5 isa fdetailview in section taken on the line 55 of Fig.3; and i r F'g. 6 is an edge elevation showing the hinge fitting connecting the secondary side; member of the stanchion to the bottom member thereof.

. The numeral 7 indicates a stall structure,

as an entirety, with'the exception of the top bar 8 and the partition 9 between the manger and stall. The improved stanchion is of the floating type and is held suspended over the partition 9'by a short chain 10 anchored to the top bar 8. A short chain 11 attached to the bottom member of thestanchion and anchored to the partition'9 limits the swinging movement of said stanchion.

The stanchion, as shown, comprises main and secondary .side members12 and 13, re

spec-tively, in parallel arrangement 4 and top:

and bottom members 14 andv 15, respectively,

which extend perpendicular to said side members. All of the members of the stanchion12, 13,14 and 15 are formed from bars, the rounded backsof which form the inner edge portions of the stanchion and the flanges thereof are turned outward in the plane of the stanchion.

I The top'and bottom members '14 and 15 are integral with the main in said figurep This hinge fitting 16 is U shaped .in cross section with the lower end portion of the secondary side member 13'and the free end portion ofthe bottom member 15 extending between the flanges thereof and having a relatively tight fit therewith. The

V flangesof the hin g e fitting 16 are relatively wide and. completely overlap the flanges of the. secondary side memberf 13 and bottom member 15. a The back of the hinge fitting 16 extends V obliquely between the secondary side member 13 and vthebottom member 15 and affords a brace, the upperfendof-which engagesthe back of "said-secondary side member and the lower end of which engages theback of the bottom member 15 when "said secondary side 'IIlGhlbf'iS closed, as best shownlby full lines .in Fig. 3. A" pair of rivets 17 inserted thrc iugh, aligned, bores in the overlapping flan esof the secondary side member 13 and hinge, fitting 16' rigidly fconnect said side member and binge fitting. Ahinge bolt 18 is v inserted throughalignedbores in the flanges of the bottom member 15" and hinge fitting 16 near the lower or rear end of the back of said fitting and connectsthe same tothe bottom member 15"for hinge-acting movements to permit op ningiand closing move-' ments of the secondary side bar 13."

It will be noted by reference to Fig. 3 that the bottom member 15 is provided with a plurality of longitudinallyspaced bores 19 through anyone pair of which the pivot bolt18' may be inserted to adjustably connect the hinge .fitting 16' to said bottom mam-1 ber to position the secondary'isidemember 13 different distances from the main side member 1 2 to. vary the width ofthestanQ 5 chion. It will also be noted by reference to Fig. 3 that the pivot bolt 18 extends through the upper link of the chain 11 at a point between the flanges of said bottom member and connects said chain to the stanchion.

The flanges of the hingefitting 16 have long contact with the outer faces of the flanges of the bottom member 15 at all times and in allpositions of the secondary side member ,13 and thereby securely hold the same against lateral or angular twisting movements. The lower end of the secondary side member 13 is spaced above the back of the bottom member 15156 permit the re quired pivotal movement of the hinge fit-,

ting 16 during the opening and closing of the secondary side member 13' and the outer lower corners ofthe flanges of the secondary side member 13 engage the back of the bot-v tom member 15 as a positive stop to limit the opening movement of said secondary side member.

Nested with the free end portion of the top bar 14 is a U-shaped fitting 20 that is rigidly but detachably secured thereto by inner and outer nut-equipped bolts 21 passed through aligned bores'in' the flanges of'said member and fitting. By reference to Fig.

3 it will be-noted that there is a plurality of longitudinally spaced bores 22 in the flanges of the top member 14 for the bolts 21 to permit longitudinal adjustment of said fitting on the top member 14. These bores 22 are so arranged in respect to the bores 19'that the secondary side bar 13' is always kept in parallel arrangement with the main side bar 12 duringthe adjustment of the hinge fitting 16 and the fitting 20 on the bottom member 15 and top member 16, respectively. 7

The outer end of theback of the fitting 20 is shaped to fit around the back of the secondary side member '13 .as a stop'23 for the secondary side member 13, when closed.

The flanges of the fitting 20 are extended outward of the stop 23 to afford a pair of diverging guide prongs 24 for directing the,

secondary side member 14 to its seat 23 and for holding said side member against lateral movement in respect tothe top member 14.

Alatch in the form of a hook 25 is mounted between the flanges of the top member 14 .and its shank is pivotally connected thereto by the inner bolt 21 for vertical swinging movement. This latch 25 is gravity held in an operative 'position in which' it overlies the upper endof the secondary side member 13. and engagestheback thereof between its flanges to .hold said side member closed against the'stop 23, I The width of the latch 25 is such as to snugly fit between the flanges of the top member 14 and is held thereby against lateral'movement, as best shown in. Fi s; 2" and 3.- i V I 6n the outer endof the latch 25f'is a cam surface 26arranged to be engaged bythe' the latch '25 with the inner bolt 21 extending therethrough, as best shown in Figs. 2 and 3. It will also be noted that the latch 25 at its-lcrotclrhas oblique engagement with the lower link of the chain 10 and holds the same in j crank-acting arrangement therewith so that the weight of the stanchion on the said link holds thelat-ch 25 closed so that the same cannot be accidentally released. Obviously, the fitting 20 and latch 25rigidly connect the secondary side member 13 and top member 14 when said secondary side member is closed.

One of the primary objects of pivoting the hinge fitting '16 at its lower or inner corner to the bottom member 15 with its side flanges overlapping the sides of said bottom member is to securely hold the secondary'side member 15 for straight-line swinging movement and against lateral angular movement from said bottom member so that the upper or free end of the secondary side member will be directed between the guide prongs 24 during its closing movement for interlocking engagement with the latch25. It will thus be seen that the operator in closing the secondary side member 13 simply swings the same inward'without giving any thought as to directing the same to the latch 25 with which saidside member automatically interlocks at the completionof its'closing movement.

lVhat I claim is:

1. A stanchion comprising main and secondary side members, top and bottom members, a latch in the top member for the secondary side member, and a hinge'fitting connecting the secondary side member to the bottom member for outward swinging movement from a closedposition in the plane of the stanchion, said hinge fitting having guide flanges that engage the bottom member and direct the secondary side member to the latch during its closing movement.

side flanges rigidly secured to the secondary side member, extending thereb'elow with the bottom member extending longitudinally having itslower link inserted. between. the prongs of the bifurcated pivoted end of therebetween, said side flanges being materially wider than the secondary side member, pivoted to the bottom member between the main and secondary side members and offset materially toward the main side member from the secondary side member, whereby endwise movement is imparted to the secondary side member during its opening and closing movements, said side flanges extending from their pivotal connection with the bottom member to substantially the outer face of the secondary side member and having long bearing contact with the sides of said bottom member longitudinally thereof to securely hold said secondary side member against lateral or angular movements transversely of the plane of the stanchion and with the upper end of the secondary side member in alignment with. the top member, and a latch for securing the secondary side member to the top member.
